o. GANIO CRIMPING MACHINE Filed Sept. 12, 1935 2 Sheets-Sheet 2 Patented Nov. 10, 1936 UNITED STATES PATENT OFFICE 9 Claims.

This invention relates to crimping machines and more particularly to a device to crimp the petals of artificial flowers.

The main object of the invention is to provide a machine to form the petals of an artificial flower with a series of undulations similar to the undulations appearing on the petals of a real flower.

A further object of the invention is to provide a bed plate with a seriesof corrugations on its top face and a presser arm having similar corrugations for crimping a blank sheet of material.

A further object of the invention is to provide a roller having a series of corrugations on its periphery to give the crimped material a permanent set.

A further object of the invention is to con struct a device of this kind having means to bend the material from which the artificial flowers are made in regular undulations and means to give the bent material a permanent set.

With the above and other objects in view, as will be presently apparent, the invention consists of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawlugs and specifically claimed.

Figure l is a side view of the crimping machine showing the presser arm in an opened position.

Figure 2 is a. similar view as Figure 1 but showing the presser arm in a closed position.

Figure 3 is a top view of the machine.

Figure 4 is a top view of the bed of the machine.

Figure 5 is a front view of the bed plate.

Figure 6 is a rear view of the bed plate.

Figure 7 is a top view of the presser arm.

Figure 8 is a bottom View of the presser arm.

Figure 9 is a sectional detail showing the presser arm in contact with the bed of the machine with a portion of the flower petal between the two elements.

Figure 10 is a view of the roller.

Figure 11 is a view of the flower partly crimped.

Referring now to the drawings in detail, numeral l designates the stand of the machine, 2 the bed plate fastened thereto and 3 the presser arm. Pivoted to the sides of the bed plate is a forked lever 4 for actuating the presser arm and the roller 5.

The bed plate comprises a hollow member having a curved top 6 formed with a series of corrugations I. The presser arm 3 is curved at the forward end 8 to correspond to the curvature of the top of the bed plate and the underside of the said arm is also provided with corrugations 9 to match the corrugations formed in the bed plate. The rear of the arm is offset as at [0 and furnished with two bearing members I l in which is journalled the roller 5 having a set of corrugations E2 on its periphery corresponding to the corrugations formed in the bed plate. A pin I3 is embedded in the offset portion of the arm with its ends projecting in the elongated slots M of the lever 4. A spring I5 is interposed between the forked portion I6 of the lever and the raised portion ll of the presser arm for a purpose to be later described. Bosses l9 and 2B are provided on the raised portion I8 of the arm and the forked portion [6 of the lever to properly position the spring. At both ends of the spring are asbestos washers 2| and 22 in order to heat insulate the handle member 23 from the rest of the structure. Within the interior of the bed plate can be placed a heating element such as a gas burner or any other source of heat to keep the device at constant relatively high temperature.

In operation a blank piece of material A is cut in the segmental form shown in Figure 11. Each segment represents a petal of a flower. The segments of material are then consecutively placed on the bed plate 2 and the lever 4 moved to the left. This will cause the roller 5 to ride on the top of the bed plate as shown in Figure 2 and swing the presser arm against the bed plate and emboss the material to correspond to the corrugations formed in the bed plate and presser arm. The spring 15 bearing on the presser arm will supply sufficient pressure to form the corrugations B in the segments A. As the presser arm moves to the left the petals will in addition wrinkle as at C at right angles to the corrugations B.

Numeral 26 designates a stop to regulate the anti-clockwise movement of the lever and 21 the stop for the clockwise movement.

It will thus be seen that I have provided a simple, efiicient and practical device for the purpose specified. It is obvious that changes may be made in the form and construction of the invention without departing from the principles involved therein. It is not, therefore, desired to confine the invention to the exact form herein shown and described but it is desired to include all such as come within the scope of the appended claims.
